Clocks Made From Vinyl Records

The theory that vinyl records can audibly represent lower frequencies that compact discs cannot (making the recording sound "warmer") is disputed by some and accepted by others. According to Red Book specifications, the compact disc has a frequency response up to 22,050 Hz. The average human auditory system is sensitive to frequencies from 20 Hz to a maximum of around 20,000 Hz. The upper and lower frequency limits of human hearing vary per person.
